The Physics Behind Waterslides

I visited that Park. A lot Grew up about 45 minutes away from there. Had friends who "lifeguarded" there.

A little bit of background for everyone: the park was located in Vernon, New Jersey (USA), built into the side of a small mountain, hence it's successor's name being Mountain Creek. It was a combination water park / Ski resort, depending on the time of the year.

Perhaps one of the best ways to think about this place is to imagine your favourite water park, saying to yourself "Gee, that ride is great, but I wish I could do...blah...which is prohibited by the rules and the lifeguards would throw me out.". Now imagine that same situation, except that there was no getting thrown out and no one cared about the rules. It was the inmates running the asylum a lot of times. Sure, it made it a metric ton of fun, but the injuries were often severe. Broken legs, dislocated everything, electrocutions....the ambulance was in very frequent use in that place. Some of it was the ride design, as the safeguards and engineering just weren't there. The rest....well, for insance, they had a "Cliff Dive". It was just that....a rocky outcropping about 35' above the main pool. They had weight restrictions, height restrictions, warnings about this and that....and it was all roundly ignored. The lifeguards were supposed to keep the landing area clear, but sometimes they screwed up and damn near had one person landing on another. Oh, and they warned you not to straight dive in, as you could theoretically hit the bottom. Theory, my ass. You could do it pretty easily. As I said....the engineering wasn't. They ran that park cheap, charged a decent amount for admission, and smiled all the way to the bank.

But, as bad as it was, there were hundreds of thousands of folks who came though there with little more than a smile and some sunburn. For a grabasstic teenager, it was a Paradise.
